A rail workers' union has called for "urgent intervention" by the transport secretary to help resolve the Southern Rail dispute.
The RMT has written to Chris Grayling urging him to convene talks with all sides in the 16-month-long row over staffing and driver-only trains.
Union leaders met Southern bosses this week, but the talks "stalled".
The RMT had "frank talks" with Mr Grayling in July but said all parties must get "everything on the table".
Southern's parent firm, Govia Thameslink Railway (GTR) had said the RMT did not bring any new proposals to Monday's meeting and were unwilling to explore offers the company has made to settle the dispute.
In a message, human resources director Andy Bindon wrote: "No agreements could be reached and no further talks are currently planned with the RMT."
